Arbiter Agent Skills

Cross-platform agent skills for Claude Code, Codex CLI, and Gemini CLI. By Posthuman Resources LLC.

Skills

Browser Buddy

Browser automation wrapping Vercel's agent-browser CLI. Navigate pages, fill forms, click buttons, take screenshots, scrape structured data, and automate browser workflows.

Artistic Vision

Image generation via Nano Banana (Google Gemini image models) and local image processing via Sharp, ImageMagick, and FFmpeg. Generate from prompts, edit existing images, create transparent assets, resize, convert, and batch process.

Git Ideas

Opinionated git workflow management. Atomic one-idea-per-commit methodology, worktrees for parallel development, change stacking across dependent branches, GitHub PR workflows, and merge strategies.

Development

This repo is a Bun workspace. To get started:

bun install

Each plugin under plugins/* is a workspace member. The root package is private and not published to npm; distribution happens via the Git repo itself (see Installation above).
